Title: 8.45pm Just blown the DOGBOX!!!
Post by: DRAGON on May 26, 2006, 09:13:57 PM
Fitted the Guru Motorsport Dog Box today. Just went out to do final mapping at about 7500rpm and 2.2bar BANG.
I thought the engine had gone, but it was fine although 4th gear is just a grinding mess, luckly Jeremy limped it back to the workshop in 5th gear.
Checking the datalogs the engine went to over 11,000 rpm after the gearbox broke!!
The engine is an absolute animal, I thought dog boxes were strong!!! But not sure what we can do before RotorStock. Just put a stock box in and see how we get on.
I\'m going out for a few beers now  :mad:  :mad:  :mad:

We wont be able to run that much boost anyway. Because the injectors went to 90% before peak power and that is with 6 850cc and 2 550cc with 90psi fuel pressure!

Oh man that is one hell of a monster, just how much bhp/ftlb was it designed to live with ???? Certainly interesting to know how much the stock gearbox can handle. Can you get replacement bits for 4th ???

Sorry for your loss !
